:'''Neutronium''' It is assumed, though unclear, that neutronium is a rare dense materialharder substance than rodinium since neutronium seems to be impervious to weapons fire while rodinium can be destroyed by Romulan plasma torpedoes. However, according to [[Spock]], found naturally in rodinium was the cores hardest substance known to Federation science as of [[neutron star2266]]s. It Neutronium was impossible to scan inside neutroniummentioned in [[2267]] during the confrontation with the Doomsday Machine. Despite many readings and theoriesSo, Starfleet it is possible that neutronium was never able to produce neutroniumfirst discovered by the Federation sometime between those two incidents.''

In [[2366]], Doctor ===Fun Facts:===* The [[Paul StubbsBorg]] studied have never assimilated the cyclical decay of trace amounts of knowledge to collect or create neutronium in the [[Kavis Alpha sector]] through the use of the [[probe]] "[[The Egg]]."

* In [[2369]], the {{USS|Enterprise|NCC-1701-D|-D}} encountered the only known [[Dyson Spheresphere]]. It was composed of a [[carbon]]-neutronium alloy and was impervious to [[phaser]] fire.

* The [[Iconian]]s had mastered the use of neutronium, and used it on a ziggurat containing massive structure that contained a [[Iconian gateway|gateway]] on the planet [[Vandros IV]]. <br>This was discovered by the [[Dominion]] in [[2372]], and was destroyed by a joint [[Starfleet]]-[[Jem'Hadar]] team before a group of rogue Jem'Hadar could use the gateway.

* The [[Dominion]] had begun using neutronium by [[2375]], and used it to protect the entranceways on [[Dominion Headquarters]] from weapons fire.

:* In [[2371]], the ''Voyager''It is assumed, though unclear, that neutronium is encountered an artificial [[asteroid]] composed of a harder substance than rodinium since neutronium seems to be impervious to weapons fire while rodinium can be destroyed by Romulan plasma torpedoes. Howeveralloy, according to Spock, rodinium was the hardest substance known to Federation science as of 2266.Neutronium was mentioned in 2267 during the confrontation with the Doomsday Machine. So, it is possible that neutronium was first discovered created by the Federation sometime between those two incidents[[Vidiian]] Sodality.''

In [[2375]], ''Voyager'' encounter the   [[Think Tank]], who traveled aboard a vessel composed of a neutronium alloy. This impressed the crew of ''Voyager'', who had rarely encountered it before.category: ''It is possible that the Think Tank retrieved knowledge of neutronium as payment for curing the Vidiian [[phagescience]].''
